' Application filed September 6, 1927. Serial No. 217,761.

It is the object of my invention to provide new andimproved shelving of knock-down nature so arranged that shelves maybe readily removed for cleaning purposes andthe structure readily reassembled in such manner as to make a rigid structure further, to provide ready means for releasably connecting the shelving with its supports 111 manner to prevent relative rotation between the shelves and the supports; and, further, to provide novel means whereby the shelf is held against rotation to its support in a horizontal plane but is readily releasable in a vertical plane, and whereby further cavities in the supporting portions of the'supports are avoided to prevent lodgment of substances likely to cause an unclean condition.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter: I p

Posts'21 are suitably positioned or secured in place, and are provided with lower socketpieces 22 secured to the floor and provided with sockets in which the lower ends of the posts are received, and upper socket-pieces 23 secured to the ceiling, the upperend of the post being threaded andhaving a nut 24 threaded thereabout for coaction with the upper socket-piece for securing the post in zontal plane. The horizontal wings of the 1 angle bars 28 are secured to the top surfaces of the corner-pieces. The slats are of the same thickness as the horizontal wings, and are secured on top of the horizontal wings ofthe angle-bars 27, which places the upper q '75 of the horizontal wings of'the angle-bars 28 surfaces of said slats and the upper surfaces in thesame horizontal plane. The vertical wings of the angle-bars depend below'the corner-pieces. The 'cornei pieces, angle-bars and slats are rigidly secured together, as by rivetingor welding or in other manner;

Corner-supports 31 respectively comprise a head 32 and a flange 33 extending laterally in the angleof the corner at which said corner-support is placed. The corner-piece at the corner of the shelf arranged to rest on this flange, and the depending wings of the angle-bars at said corner of the shelf, which form depending flanges of the shelf, are received at the respective ends of said flange 33 extending from the corner-support,the inner side faces of said depending wings abutting against the respective ends of said flange for preventing relative rotation between theshelf and the corner-support. Said depending wings are received in rabbits 34 between the respective ends of said flange of said corner-support and the sides of the head. The sides .of the head are at right angles to each other and in line with the right angular edge-faces of the shelf.

The corner of the shelf isprovided with a recess 35 in which the corner-support is received. The corner-support has end walls 36 which are at right angles to each other, and a diagonal wall 37 between said end walls, I

the corner-piece of the shelf having corresponding walls 38, 39, respectively The ends 'of the respective angle-bars at said corner are in alinement withsaid walls 38 'and the:

, posts, as by means of set bolts 42 in threaded apertures in the wall of said bores for clamping the corner-support to the posts at desired elevation. v

I The shelves may be made of desirable lengths vand widths,there being preferably a corner-support-atfleach corner of the shelf. The top surfaces of'the corner supports and the top ,su'rfacesof the'slats and of the horizontal wings of the angle bars 28 are preferably in the same horizontal plane, so .that' the entire areacbetween posts may beutilized for shelf purposes. The top supporting surfaces "off'the corner-supports and of the shelves are in' the same horizontal plane threughou't "the area betweeniposts.

f TH it, is desired to arrange a series of shelves end to end, 'sin le corner-supports are provided for the en s'of the shelving and double 'corner-supports 131 are provided betweenthe endsof proximateshelves. (SeeFigs. 2, 9 and 10,) These vdouble corner-supports are provided with elongated heads 132, from which supporting flanges 133 extend horizontally in the angles between proximate shelves; the depending wings at the proximate ends ofthe adjacent shelves being re- -cei-ved in a slot 134 betweenthe proximate -ehds0f the horizontal flanges extending from said head 132. f'lhis slot serves the purpose ef two of the rabbets 34. The; head L32 ispro with abore 141'in-which the post is receivedJfThe dduble corner-supports are ad justably' secured to the post in the same-inanner as are the single corner supports. The

parts ofthe double corner-support are desig- 5'0 mated byreference numerals similar to the reference numerals designating similar parts of the single corner-support, but :raised to the series 100.

Hit isdesired to arrange shelvesat right 'angles to:eachother, a;corner-support 231 which has a solid head 232,: andissecu-red to 'the depending. wingof the proximate shelf,

intermediate of the ends of said shelf, as by -=means :of bolts 242 (see Figs. 2,,11 andl2).

The topofthis head is preferably on a level with themdjacentslats so as to provide a "shelf having upper supporting surfaces which a-re'level throughout.

rsa'id shelf and said corner-support.

support-is secured, forms a slot 234 i'nwhich the depending end wing of the shelf supported by said corner-support is received. The parts-of the shelf-supported cornensupport are designated-byreference numerals similar to the reference numerals designating similar parts of the single corner-support, but-raised to the series 200.

The corner-supports v and corner-pieces may be of cast metal and the angle-bars and straps may. also .be o'fsinetalfl The shelves may be suitablygalvanized, tinned, or otherwise coated after thesarne have been fabricated. My improved device iseinployed in various relationsand is especially adapted for" use as meat-racks and-forsupporting products in themeat industry.

The construction and arrangement of the corner-supports and 'of the" shelf-parts con1-' pleniental thereto are such that the shelving 1s rigid when asse111bled\vl1ether ornot the posts are independently fixed at their tops.

The corner supportsand' the shelves are constructed to avoid cavities so as to permit ready cleaning of the same, andthe parts are so constructedand arranged that the shelves may be readily removed and re"- placed, A structure is further provided which is firm andrigid and is "especially strong for readily supporting 'the"gre'at weights. to which shelving of this kind issubjected. r
